Oman, who defeated Iraq 6-3 in its opening match in Pattaya, Thailand on Sunday, will face Team Melli in Group D on Tuesday.
"First of all, I want to say thanks to my players, they did a good job. The match was not easy. We were well prepared because we knew we were going to play with a strong team and my players did a good job and played as we planned,” Hilal said.
“Now our concentration goes to the game against Iran," he added.
The championship also acts as the qualification tournament for Asian teams to the 2019 FIFA Beach Soccer World Cup in Paraguay; the top three teams will qualify.
